Claims.

In large, lined, cylindrical metal tanks or vessels with conical bottoms and tops and equipped with appropriate admission and discharge conduits employed, for example, as set forth in my copending patent application Serial No. 470,992, Lined Containers, filed January 1, 1943, now Patent No. 2,460,052, dated January 25, 1949, in the regeneration or restoration of catalysts in powdered or nely divided form used, for instance, in the production of high-octane fuel for internal-combustion engines, the heat, pressure, abrasive effects and gas flows prevailing in such container render the protection of the metal enclosure or receptacle against the development of dangerous hot-spots in the metal wall a problem or diiculty the solution of which has caused much trouble and anxiety.

Such catalyst is an eicient abradant and its coating of carbon deposited thereon during the performance of its catalytic function is burned ofi" and thus disposed of in such tank, the temperature therein reaching approximately 1000o F.-1200 F. and the gas or fluid pressure in such vessel is about 5 pounds per square-inch, such gas charged with the catalyst to be treated also having a swirling action, and the protective lining of'such a container, which is frequently of 45 ft. in diameter and 90 ft. high, must under all varying conditionseffectively shield and protect the metal-shell.

Obviously, the internal temperature is high and the gases at such temperature and their contained abradant are in direct contact with the refractory-tile lining, and the heat of such tiles must be prevented from reaching the metal shell in substantial or destructive measure, this being accomplished by suitable insulation completely filling the volumetric space, not otherwise occupied, between such refractory-lining and the wall.

The pressure varies greatly and suddenly tending to set up serious vibrations and dislodgements of the tiles, especially those lining the lower, inverted-cone bottom-wall of the vessel, and, accordingly, the novel and improved means embodying the present invention have been employed to solve such problem.

The indicated 5 pound pressure may abruptly and substantially-instantaneously change to two pounds or three pounds per square-inch, but this quick variation while instantly applicable to the inner or upper surfaces of such tiles lining the bottom cone does'not have corresponding immediate access to the under or outer surfaces of these tiles, so that, since the area of the back or under surface of such a tile is approximately y fty square-inches, the instantaneous force on an individual tile with a 3 pound differential would result in a pressure of one hundred and fifty "pounds tending to dislodge the tile, and, in like manner, if the differential were 5 pounds per square-inch that same displacing and unseating force would reach a magnitude of approximately two hundred and fifty pounds. p

In addition, owing to the swirling or circumrotatory action of the catalyst-charged,V gaseous contents of the tank, there is a distinct tendency to dislodge the tiles additionally, horizontally, circularly on their supports and the current invention provides means to preclude the occurrence of any detrimental action or effects from such a cause.

Stated succinctly one of the main objects of the present invention is to provide means for lining the side walls and the bottoms of such containers and the walls of associated pipes or conduits in a manner to give satisfactory and prolonger service regardless of the occurrence of the conditions stated above.

To enable those skilled in this art to understand the invention from both structural and functional standpoints, present preferred em#- bodiments thereof have been illustrated in the accompanying drawings forming a part of this specification and to which reference should'be had in connection with the following detailed description, and for simplicitylike reference numerals have been employed in the several views of the drawing to designate the same parts.

In these drawings:

Figure 1 is a fragmentary vertical sectio through the bottom, inverted-cone portion 'of the lined container or tank;

Figure 2 is a partial horizontal section of the same construction on line 2 2 of Figure 1 and with the insulation-lining omitted to more clearly depict the other structural elements;

Figure 3 presents an enlarged portion of `Figure l;

Figure 4 is a section on line 4--4 of Figure 1;

Figure 5 is a cross-section of a pipe or conduit embodying the current invention; and

Figure 6 is a fragmentary section on `an enlarged scale taken through the wall of, and lengthwise the axis of, the conduit illustrated in Figure 5.

Referring first to Figures 1 to 4 inclusive, it will be noted that the conical metal-wall of the sloping bottom of the container is designated as Il and at intervals along it and at different levels circular rows of metal-supports I2 are Welded to its inner or upper surface and to the opposite anges of each such member I2 the longitudinally-slotted ends I3 of curved bar-sections I5 are bolted at I4, such aligned bars of any one annular set constituting in effect a single, circular, sectional bar, and it will be considered as such herein, with the slot expansion and contraction compensating-means 1 at eachl such support I2, theseiring bars IE5 being concentricvith wall I I and With their bodies disposed vertically, as clearly shown in Figures 1 and 3.

Supported by and slidably mounted on 'each such circular-bar I5 is a number'ofspacedapart brackets or clips I6 located "aroundtheientire circle, each such bracket having -an outwardly extended arm I'I resting and bearing on the top edge of its bar I5, such arm y'having andovvnf Wardly-extended, terminal projection I8 (Fig. 3) overlapping, and normally contacting with, the upper portion of the back or outer face of the bai.

In this case, as indicated in Figure 5, the refractory bricks or tiles of any annular row are fitted tight together without any expansion joints between them and such tiles are not longitudinally tapered because the pipe is of uniform diameter throughout.

The object of the absence of such expansionjoints is to utilize the circumferential enlargement of such rows under heat to create a greater pressure of the refractory-tiles against the insulation-lining to force the latter outwardly into firmer contact with the interior surface of the metal-shell to bar or exclude the fiuid or gaseous contents of the tank from having access thereto, which, if permitted to occur, would probably result in serious damage.

This conduit construction also uses the spacers |33 between the brackets or clips I 5 and the elevations or projections |34 on the supporting-bars ||5 on opposite sides of the parts H5, such elements |34, in this case, being indicated and shown as employed with each bracket, but, in some cases it is feasible and desirable to employ them with a lesser number of the brackets.

Those acquainted with this art will readily understand that this invention as defined hereinafter is not necessarily limited and restricted to the precise details of structure set forth, and that reasonable modications may be resorted to without departure from the heart and essence of the invention and without the loss or sacrifice of its substantial benefits and advantages.
